Trend lines are shown when slope is significantly different from 0 at the p < 0.05 level. An orange line signifies an overall positive trend, and purple signifies a negative trend. To minimize bias introduced by small sample size, no trend is fit when N < 30. Dashed lines represent mean values of time series unless the indicator is an anomaly, in which case the dashed line is equal to 0. Shaded regions indicate the past ten years. If there are no new data for 2018, the shaded region will still cover this time period.

Common tern productivity

Despite the overall warming trend in the GOM, common terns can have good productivity years, suggesting in some years at least, forage fish can still occur in reasonable abundance in traditional areas. In the long term, we hope this will continue to hold true. A concern will be how frequent the hot (poor) years are.

Shelfwide Indicators

Protected species

Harbor porpoise bycatch continues to be quite low and has been low for a number of years now, so I don’t think it is important to include anymore. At one point we had discussed putting in representative figures of marine mammal distribution available on a NEFSC website, but perhaps just mentioning the link somewhere on the page would be better.

Notes on upcoming indicators- Salmon ecosystem indicator - in the works but won’t be ready for this SOE. Seals - diet work underway but unpublished so don’t want to include. but can reference generally in text. - their diet appears to lean on non-commercial fish far more than commercially important species, we can try out some text and see what Kimbelry Murray feels comfortable with.

Forage fish energy content

Notably, the energy density Atlantic herring was lower (5.69 +/- 0.07 kJ/g wet weight) than earlier studies (10.6-9.4 kJ/ g wet weight). Silver hake, sandlance, lolligo and Illex were also lower than previous estimates. Energy density of Alewife, butterfish and Atlantic mackerel were higher than earlier estimates. Sampling and laboratory analysis is ongoing, with the goal of continuing routine monitoring of energy density of these species.
